Near the beginning of the third Bremen lecture, entitled "The Danger", Heidegger points out that we are inept both at thinking the worlding of the world on its own terms and at corresponding to this event. In a marginal note he enigmatically includes the term "Ereignis", presumably referring to what it would mean to correspond to the worlding of the world on its own terms. Because of this ineptitude we need assistance in understanding the event of world disclosure and so we turn to an unavoidable knowingly erroneous path of thought but, "because we go along it knowingly we can turn back at any time".
